Mantine

With Mantine finally getting access to a useful Flying-type STAB move that isn't Hidden Power Flying, it has established a very solid niche for itself in the NU metagame. STAB-boosted Air Slash allows it to break through Grass-types such as Roselia and effectively dispatch Ludicolo, achievements not many other rain sweepers can boast. This position as one of the best Ludicolo counters also makes it a solid option to combat opposing rain teams. Two useful abilities allow it to compete in both offensive and defensive roles, with Swift Swim giving it the speed to take out many threats while Water Absorb allows it to wall and defeat rain sweepers and other Water-types.
